A molten nitrile resin is injected into the cavity 5 from a die nozzle 6 and, then, the molds 2,4 are perfectly clamped to form a tube container head part 8 to one end of the tube container body part 2 from the resin. That is, the head part 8 consists of a fine neck like mouth part 9 and the fan-shaped shoulder part 10 continued thereto and integrally formed along with the body part 2 to be bonded to the body part 2.
